ABSTRACT:
The invention relates to a method and apparatus for automatically reading bar code symbols. One aspect of the present invention concerns a method of reading bar code symbols using an automatic hand-holdable bar code symbol reading device that includes a hand-holdable housing containing operative elements which provide an object detection field and a scan field each defined external to the housing. The the presence of an object is automatically detected within the object detection field by sensing object sensing energy reflected off the object. In response, the hand-holdable device automatically detects the presence of a bar code within the scan field using a laser. Then, in automatic response to the detection of a bar code, the automatic hand-holdable bar code symbol reading device reads the detected bar code in the scan field by producing scan data signals from the detected bar code and thereafter collecting and analyzing the same.
